High Performance Wafer Butterfly Valve
• Excellent durability of seat part and low operating torque by non-rubbing characteristics with triple offset construction.
• Bi-directional zero leakage service by resilient metal sealing and torque seating.
• Unrestricted selection of face to face dimensions for API, ASME (ANSI), BS, ISO, etc. and perfect interchangeability of gate, ball, plug, high performance butterfly, and other valves.
• Low emission by quarter turn construction and good performance at automation by virtue of low operating torque and low cost. -
